Strait of Hormuz
Strait of Hormuz: a major Gulf energy route under severe security pressure
The Strait of Hormuz is the sea passage linking the Persian Gulf with the Gulf of Oman. Before the US-Iran war, it carried about one-fifth of global energy supplies. September exports through it were estimated at around 6.5 million barrels a day, though traffic has fallen sharply from roughly 125 commodity vessels a day before the war.
Reporting on 21 and 22 September describes mostly suspended commercial traffic, attacks and harassment involving tankers, and a JMIC threat level of severe. At least five tanker incidents were reported since 16 September. Projectiles injured crew, but UKMTO has not attributed the attacks. Tankers are also using a narrow Omani coastal corridor under US naval protection, sometimes with AIS off. Qatar, Türkiye and France are pressing diplomacy, while Iran says it could reopen the waterway within seven days if US military pressure and the blockade of Iranian ports ease.
